Fig. 9 is a verticalcross-sectional view of the machine on line 3 of Fig. 1, looking in thedirection of the arrow, showing a side view of the barb-compressingmechanism. Figs. 10, 11, 12, 13, and 14 are detailed views of the barbbending and folding mechanism, showing the barb in the various stages offormation, and Fig. 15 is a view ofa section of a pair of strand-wireshaving a barb applied thereon, being a'production of this machine.

Referring to the drawings, B represents the principal bed of themachine, intended to be supported on suitable legs, and B is a second.-ary bed or plate, secured to the upper face of bed B, for supporting thebarb bending, folding, and cutting mechanism.

S is'the main shaft,arranged. above and along one side of bed B in thestandard-boxes B B, and has keyed on it sprocket-wheel m, to which poweris applied to drive said shaft, cams C, O, and O, eccentrics O E,crank-disk D, and mitergear e.

A is a stationary barb-point cutter, secured in a standard-box on bed Bby means of capplate H and 011 a line with the space between thestrand-wires.

A is an oscillating barbpoint cutter, arranged. to shear with stationarycutter A, and is secured by means of cap-plate F to the upper side oflever F, fulcrumed at Z between standard lugs d d, and connected at itsopposite end, through the medium of an-eccentric strap,with eccentric Eon shaft S, by means of which said lever and its cutter A is oscillated.(See Figs. 1 and 5.)

H is a lever fulcrumed near its center at Z, between a pair ofstandard-lugs, d d, on bed B, and having its rear end provided with aroller-wrist, A, for-operating in the channel of cam O, and its oppositeend having a chamber for holding the strandwire guides adapted to be adjustably held thereon by set-screws. (See Figs. 1, 2, and 5.) The saidstrand-wire guide consists of the sleeve I, for containing the centert,provided with oppositelongitudinal channels, and the center 15', havinga pair of longi tudinal holes corresponding with the channels in centert, through whichchannels and holes the strandwires W are threaded. (SeeFigs. 2,4, and 8.) These centers tand t are secured within said sleeveby set-screws.

It and R are a pair of reciprocating barbprod benders arranged in box Dand held therein by means of the cap-plate D D is a rock-shaft arrangedin an extending box of cap D and has on its inner end a disk, K,provided on its face with a pair of opposite pins,f and f, respectivelyconnected to the reciprocating barbbenders R R. (See Figs. 6 and 7.) Thebarb-benderR is provided with an opening, as shown in Fig. 7, for thepurpose of permittingpinf to pass through it to connect with theopposite barb-bender, It, and so barb-bender R can reciprocate. Theopposite end of shaft 1) is provided with crank L, having a roller-wristfor operating in the channel ofeam C. The form of said eam-ehan nel issuch that said shaft D is intermittingly rocked when said cam rotates,and through its connection with the barb-benders R It will reciprocatethem in opposite directions, for the purpose hereinafter described.

S is a rock shaft secured in a box on bed B, and has secured on itsouter end the arm L, for engaging cam C on shaft S, and has secured onits inner end the oscillating barb-prod'bending arm R".

S is aspring for holding arm L engaged with cam 0-. (See Figs. 2 and 8.)\Vhen said cam rotates, the barbprodbending arm It will beintermittingly oscillated, for the purpose hereinafter stated.

N N are a pair of ordinary barb-wirefeed rolls having their shaftsgeared together and intermittingly driven by shaft S, through the mediumof crank-disk D, pitman l and a pawl-and-ratchet mechanism, in theordinary manner, (see Fig. 1,) and r is a guide for conducting thebarb-wire from said rolls between the strand-wires and cutters.

J and J arejaws forming a press for compressing the barbs properly onthe strandwires after they have been folded thereon by the barb-benders.The jaw J is stationarily fixed on bed B and jaw J" is hinged to jaw Jat its foot and rests at its upper rear side against eccentric C onshaft S, by means of which it is oscillated to open and close said jaws.

C is a curved spring secured to the upper side ofjaw J, and extends oversaid eccentric for the purpose of holding jaw J in engagement with saideccentric O.

J and J are removable interchangeable plates secured respectively to theinner face of said jaws and have their faces concaved, so when theycompress a barb they will bring its prods and strand-wires in line witheach other, (see Figs. 1 and 9,) or nearly so.

V is a barb-point guide secured to the body of the reciprocatingbarb-bender R, in a suitable recess between the benders R 1%, and isformed, as is shown in Figs. 4, S, and 10, so it will guide the barbprod properly between the benders 1% R and over the grooved lugs 0thereof. (See Figs. & and S.)

The reciprocating barb-prod benders R R are formed in such manner thateach has a depending arm overreaching the strand-wire line of themachine, (see Fig. 8,) and are respectively provided at the lower end ontheir sides facing each other with circular grooved lugs O and O, asshown in Figs. 8, 4, 8,10, 11, 12, 13, for engaging the barb-prods toassist to fold them on the strand-wires.

V is a presser-foot secured to lever II by means of standard V" and armV, as shown in Figs. 1. and 2, and is for the purpose of pressing 011the strandwires to hold them in line with their guide when thestrand-wire guide is descending. g is an outer guide or eyelet throughwhich the barb-wire is guided to the feed-rolls.

The two reciprocating barb-prod benders R and it have their outerextending ends constructed, as shown, to form depending arms having thecircular grooved lugs O and 0 respectively secured to them on theirsides facing each other and at their lower extremity, and are adapted toreciprocate only when the strand-wire guide has descended to be belowthem.

The lugs O O are not relieved from contact with the barb-prods untilthey are completely folded on the straml-wires and operate as a rest forthe prods to lie against while the strand-wire guide is ascending anddescending between them, and they change position with each otherwhenthe strand-wire guide is out from between them to fold the prodsover in opposite direction on the strand-wires.

In this machine the principal new features are in the parts that foldthe barb on the stranttwires, and consist of an oscillating strand-wireguide for elevating and lowering the strand-wires during the process offolding the barbs thereon; of a pair of oppositely-reciprocatingbarb-prod benders arranged one on either side of the strandavircs at theplace the barb is fed between the said strands, and in such manner as toengage and support a prod on either side of the strand-wires after beingsevered. from the barb-wire, and while the strand wire guide descendsand bends the two prods up they then reciprocate in opposite directionsand fold the two barbprods over the upper strand-wire, so they projectin a horizontal plane in opposite directions and hold the prods whilethe strandwire guide ascends and bends the two prods to projectdownward; of an oscillating benderarm for engaging one of thedownwardly-pro, jeeting barb-prods and bending it laterally under thelower strand-wire and support it until the strand-wire guide descendsagain, which will bend said prod upward to project in an oppositedirection from the opposite prod, thus completing the fold of the barbupon the two strand-wires, after which the strand-wire guides furtherdescend, so that the two barb-prod benders can reciprocate back to theirfirst position, and the strand wires are drawn along to carry the saidbarb along out of the way, so the next succeeding barb can be applied.

In operation the two strand-wires \V \V are taken from the coil, passedover a suitable guide in the ordinary manner, thence they are threadedthrough the center guides, t and 25, between the barb-prod benders,between the barb-compressing jaws, and thence to and over an ordinaryoscillating sprocket-wheel,

T, to a spooler and twister below the barbing mechanism, (not necessaryto be shown, as it forms no part of this invention,) and so that onewire will be directly above the other, as shown in Fig. 2 particularly,and are intermittingly drawn through the machine by means of saidsprocket-wheel T, inthe ordinary manner. The barb-wire is fed throughthe guide g by means of the feed-rolls N N, so as to enter between thetwo strand-wires and between the two reciprocating barb-benders R R, andwhen first fed inisin the position shown in Figs. 4 and 8, the barblying over and in the grooves of the lugs O and 0. Further rotation ofthe machine will cause the strand-wire guide I t t and strand-wires \Vtherein to de scend from the position shown in Fig. 8 to that shown inFig. 10, the cutters A A severing.

the barb from the barb-wire at the same in stant. WVhile the barb isin'the position shown in Fig. 10 the reciprocating barb-prod bendersreciprocate and change position with each other to that shown in Fig.11, thus folding the barb on the upper strand-wire. The strandwireguides, with the strand-wires, then ascend between the benders R R tothe position shown in Fig. 12, causing the benders to bend the twobarb-prods downward, one prod, W, being longer than the other. The arm Rthen moves forward and engages the long prod IV and bends it to theposition shown in Fig. 13. The strand-wireguide and strand-wires thendescend and cause the arm R to bend prod W upward, as shown in Fig. 14,and sothat it incloses the lower strand-wire and projects in theopposite direction from the other prod, and at the same time the twobarb-benders R R reciprocate and change position back to that shown inFigs. 4 and 8, finishing bending and folding the barb on thestrand-wires.

The upper end of arm R is provided'with a notch, h, for engaging saidbarb-prod, andis cutaway at the side of said notch, as shown in Fig. 2,so as not to engage the opposite prod. After the barb has passed throughsaid various stages, and is formed as shown in Fig. 14, the strand-wiresare drawn along by means of a .tak'e-u p mechanism, (not necessary to beshown,) and the barb thus formed passes between jaws J J, which compressit on the strandwires'in the proper form, and leaves it finished andapplied to the strand-wires, as shown in Fig. 15. i

Having thus described my inveutiomwhatI claim as new, and desire tosecure by Letters Patent, is as follows, to wit:
